1958年，弗朗西斯・克里克提出了中心法则，提出遗传信息从 DNA 转录为 RNA，再经翻译指导蛋白质合成，随后蛋白质参与生命活动这一流程，看似一气呵成，实则存在问题。 若仔细观察，便会发觉此流程不够简洁，RNA 的存在略显累赘。毕竟，越简单的系统往往越高效、越易实现，繁琐的系统则耗能多且不易形成。 从结构看，RNA 与 DNA ...

The team also detected adenine, guanine, cytosine, thymine and uracil — all five of the biological nucleobases, or components ...

Dworkin co-authored a paper outlining the chemical compounds scientists found in the Bennu samples. They included 14 of the ...

The illustration shows DNA being folded into a loop by an SMC motor called cohesin (in purple/blue). The purple part of the motor (with a red/green label) is the protein subunit NIPBL, which acts as a ...

This is a first for DreamWorks Animation. However, the sci-fi adventure from director Chris Sanders (who is very well liked and due for a win) is in a tight race with indie sensation “Flow ...

研究人员利用他们对分子马达的理解来改进纳米级人工马达，旨在弥合人工马达和运动蛋白之间的速度差距。 DNA纳米粒子马达就像它的名字一样：微小的人造马达利用DNA和RNA的结构，通过酶降解RNA来产生运动。简单来说，它们通过偏置布朗运动将化学能转化为机械运动。

Apple TV+ is expanding its kids and families slate with new animated series Goldie, inspired by Emily Brundige’s award-winning 2019 short film of the same name. It’s set for premiere globally ...

Since its introduction in 2002 at the 74th Academy Awards, the Best Animated Feature category has emerged as a tribute to the realm of animation, with Shrek clinching the inaugural award.

The 97th Oscars will be held on Sunday, March 2. All movie listings, titles, distributors, and credited artisans are not final and are subject to change.

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still carry the genetic fingerprint of that intermixing. Since then ...
